The decimal numeral system (also called base ten or occasionally denary) has ten as its base. It is the numerical base most widely used by modern civilizations. Modern computer hardware and software systems commonly use a binary representation internally (although many early computers‚ such as the ENIAC or the IBM 650‚ used decimal representation internally). For external use by computer specialists‚ this binary representation is sometimes presented in the related octal or hexadecimal systems. For most

------------------------------------------------- Prime number A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. A natural number greater than 1 that is not a prime number is called a composite number. For example 5 is prime‚ as only 1 and 5 divide it‚ whereas 6 is composite‚ since it has the divisors 2 and 3 in addition to 1 and 6. The fundamental theorem of arithmetic establishes the central role of primes in number theory: any integer greater than 1 can be expressed
